LEUCOSPORI. 109 



even, smooth. Stem 2.5-5 cent. (1-2 in.) long, 2-4 mm. (1-2 lin.) 

 thick, fistulose, tough, equal but attenuated at the base and not 

 rooted, even, everywhere smooth, polished, pallid-rufescent. Gills 

 adnate, obtuse behind, not much crowded, very broad, rather thick, 

 becoming pale white, edge serrulated. 



Solitary, inodorous. The pileus is easily split at the margin. It may be 

 safely distinguished from A. dryophilus by its broad, thicker, and less crowded 

 gills. The only allied species is A. nitellinus. 



In mixed wood. Coed Coch, &c. Aug. 



The plant is much darker in colour than the name would imply. Name 

 succinum, amber. Amber-coloured. Fr. Monogr, i. p. 162. Hym. Eur. p.

223. A. nummularius Fr. Pileus 4 cent. (\y, in.) and more 

 broad, pallid, variegated here and there with yellow and reddish, 

 slightly fleshy, rather plane, depressed round the obsolete umbo, 

 even. Stem 4 cent. (\y z in.) long, stuffed then hollow, smooth, 

 pallid, thickened at the apex. Gills free, somewhat distant, 

 white. 



Beautiful, arid. 



In mixed wood. Glamis, 1874. July-Oct. 



Name n-ummulus, a small coin. From some fancied resemblance to a coin 

 in shape. The name of the subgenus indicates the same. Fr. Hym. Eur. p.

224. A. esculentus Wulf. Pileus 12 mm. (# in.) and more 

 broad, ochraceous-clay, often becoming fuscous, slightly fleshy, 

 convex then plane, orbicular, obtuse, smooth, even, or when old 

 slightly striate; flesh tough, white, savoury. Stem 2.5 cent, (i 

 in.) and more long, scarcely 2 mm. (i lin.) thick, or filiform and 

 wholly equal, obsoletely fistulose, tough, tense and straight, even, 

 smooth, slightly shining, clay-yellow, with a long, perpendicular, 

 commonly smooth, tail-like root. Gills adnexed, even decurrent 

 with a very thin small tooth, then separating, very broad, almost 

 obovate, lax, somewhat distant, whitish, sometimes clay-colour. 



Gregarious but never caespitose. The tube of the stem is very narrow. 

 The gills are not so pure white as in A. tenacellus. Although it seems to 

 be well distinguished from A. tenacellus in its life-history as well as in its 

 colour, individual specimens occur which can often be determined only with 

 difficulty, and many, which appear at first sight to admit of no doubt, have 

 been ascertained, on digging up the root, to belong to A. tenacellus var. 

 stolonifer. 



In pastures and grassy places near plantations. Common. 

 April-May.
